The data fields in each record are organized into tables in the documentation, which are described in terms of their major components or elements. The first element consists of DUALabs Data Descriptor Numbers for used with DUALabs 70-series program. These are 6-digit numbers consisting of a table number (first three digits) and a line number within a table (last three digits). (Geographic codes also have 6-digit Data Descriptors, which always begin with a G.)

The second element is the tabulation title which is a description of each tabulation on the tape. The order of presentation of items on the tape is not reflected in the title.
The third element is the total number of data items or fields in the table.

The fourth element is the universe being tabulated; e.g., persons, persons 14 years and over, vacant housing units.
The fifth element constitutes the variables or stratifiers by which the universe is classified; e.g. age, sex, plumbing facilities. The name of each stratifier is preceded by the word 'By' and followed in parentheses by the number of categories of the particular stratifier.

Below the stratifier names are listed the stratifier categories (sixth element) used to classify the universe in the particular tabulation.

A hypothetical example follows:

021000 (A) POPULATION 14 YEARS OLD AND OVER BY MARITAL STATUS, RACE, AND SEX (B)

20 (C)

Count of Persons 14 Years Old and Over (D)

By: Race (2) (E) By: Sex (2) (E) By: Marital Status (5) (E)

Total: (F)

Male: (F)

021001 (A) Now Married (excludes separated)

(F)

002 (A) Widowed

(F)

003 (A) Divorced

(F)

004 (A) Separated

(F)

005 (A) Never Married

(F)

Female: (F)

006-101 (A) Repeat Marital Status (5)

(F)

Negro: (F)

011-020 (A) Same as Total (10)

(F)

Key:

A= DUALabs Data Descriptor Numbers

B= Tabulation title

C= Total number of data items in tabulation

D= Universe

E= Stratifier names and number of categories

F= Stratifier categories

Note the use of the colon following some of the stratifier categories. This indicates that there is no actual item of data on the tape for that category as such. Looking back that the example, the first item or number in the tape for tabulation 21 is for Total Males Now Married, the second item for Total Males Widowed. Following five items of Marital Status for Males, the sixth item is Total Females Now Married, the 11th item Negro Males Now Married, and so on.

At the top of each page describing the data within this file is a unit identifier. It is used to pinpoint the physical location on the tape file of the first data field described upon that page. The elements describing the position are BLOCK (a physical division of the record on tape) and CHARACTER within block.

5Respondents estimate. Value is tabulated for owner-occupied units having only one unit on the property and no business. Units in multi-unit structures and trailers are excluded as are units on farms and units on ten or more acres. Value is tabulated on a 100-percent basis in places of 50,000 or more persons, 25-percent elsewhere.

19In the original Census 8-block matrix, this field is identified as excess housing capacity, a statistic derived from the 5 percent questionnaire and calculated by subtracting persons from available rooms in tract. No Data Descriptor has been provided for this item because its usefulness is questionable. The user may provide his own Data Descriptor if he wishes or he may treat the field as padding.

A two-digit numeric code, the first digit indicating geographic division and the second the specific State within the division. Exceptions were made for Alaska and Hawaii because their codes were establish prior to their attainment of Statehood. (See listed codes.)

A one-digit numeric code describing the place within which a tract occurs. Codes are as follows:
1 Central City (incorporated) of an SMSA only.
2 Central City (incorporated) of an Urbanized Area only.
3 Central City (incorporated) of both an SMSA and an Urbanized Area.
4 Other incorporated place.
5 Unincorporated place.
6 Urban towns in New England, urban township in New Jersey and Pennsylvania and urban counties elsewhere.
7 Not a place.

A two-digit numeric code assigned to a non-metropolitan county or group of non-metropolitan counties or a one-digit alphabetic code assigned to a metropolitan county or group of metropolitan counties to form approximately 525 State Economic Areas. (For specific codes refer to the 1960 Geographic Identification Code Scheme.)
